#virtualization platform? Just what is inside an F5 BIG-IP that makes it go
vroom? **
Over the years I’ve seen some pretty wild claims about what, exactly, is
“inside” a BIG-IP that makes it go. I’ve read articles that claim it’s Linux,
that it’s based on Linux, that it’s voodoo magic. I’ve heard competitors make
up information about just about every F5 technology – TMOS, vCMP, iRules –
that enables a BIG-IP to do what it does.
There are two sources of the confusion with respect to what’s really inside an
F5 BIG-IP. The first stems, I think, from the evolution of the BIG-IP. Once
upon a time, BIG-IP was a true appliance – a pure software solution delivered
pre-deployed on pretty standard hardware. But it’s been many, many years since
that was true, since before v9 was introduced back in 2004. BIG-IP version 9
was the beginning of BIG-IP as not a true appliance, but a purpose-built
networking device. Appliances deployed on off the shelf hardware generally

networking tasks – CPU scheduling, ...
